West Ham welcome back Jesse Lingard, who was ineligible to face parent club Manchester United last time out.
Arsenal winger Bukayo Saka suffered a hamstring strain during last week's north London derby and is a doubt.
Captain Pierre-Emerick Aubameyang, who was dropped from the Gunners' last league fixture for a breach of club protocol, is expected to start.

This feels like a big game for West Ham, as a test of their top-four aspirations, and I think the underlying message from their manager David Moyes will be 'let's not lose it'. All his side need to do is stay in the mix.
